Yeah, the Rocky Saddle Dropoff, used to be the W601 until the #'s were changed to the W300 series for some reason.

The 600 series are Naches District #"s. 300 series #'s are Cle Elum. That section of trail is in the Cle Elum but the Naches used to manage it. Management lines changed. Note the 601 has now been used over in Rimrock.
